I had thought about bringing the fifth wheel as an overnight enroute and then parking it at Philmont. They have parking, but no hookups and you are expected to stay in one of the tent "cities". The tents and facilities are really good, BTW.
Since it was only one night each way and with the price of diesel, it was more economical to take the car and reserve a cabin at the RV parks.
The point I'm trying to make is that RV parks with cabins are good alternatives to hotels/motels so long as you provide your own bedding (and are typically more kid/Scout friendly). One thing I did not mention is the two RV parks also permitted tent camping immediately adjacent to the cabins. An additional thought for groups, like a Scout trek team.
